4.5 kg of garbage and so much lime will go every two minutes

First phase: Primary combustion room (Rotary Kill): Temperature 850-900 degrees

4.5 kg waste bag and 4.5 kg lime bag will be inserted every two minutes. The garbage placed in this chamber will rotate. This will be ensured that the garbage is completely burnt. The ash will come down after burning garbage. After burning the garbage, the gas will go to the next chamber.

Second phase: Second combustion room

With the help of diesel burner, the remaining flu gas will be burnt at 1100 degrees temperature. If the temperature is low in the primary and second combustion chamber, then its information is immediately reached the monitoring room and the process of inserting the plant and waste is stopped.

Third stage: Gas in spray dryer

Flu gas will be sent to spray dior. Here it will cool it from a water fountain and bring a temperature of gas up to 240 ° C. A quick decline in temperature is done due to this so that there is no harmful element in the gas again.

Fourth Phase: Multisiclone machine

The gas will be passed by a multiciclone machine. Heavy particles stored in it will be separated by rotating the gas here.

Fifth stages: dry scrubber

The gas will pass through a dry scrubber. There will be a spray of lime, activated carbon and sulfur mixture on gas. This will separate from sulfur dioxide, diaxin and mercury flu gas. After this the flu gas bag passes through the filter. Where the solid particles present in the gas will be filtered.

Sixth Stage: Weight Scrubber

In the weight scrubber, caustic soda solution will be sprayed on the gas. In this process, all acetic elements such as SOTU, SOTHRI and HCL are neutralized from gas.

Seventh stage: Gas will be released from the chimney

The flu gas will be released from a 35 -meter -high chimney in the atmosphere. This gas is completely clean. The company claims that it does not contain harmful elements. There are sensors in this chimney, which causes the quality of gas to be monitored continuously.

These agencies will monitor air quality

• The four ambient air quality monitoring systems installed by MP Pollution Control Board in the Celebrating Plant Complex will check air quality.
• Central Pollution Control Board officials will be present.
• National Environmental Engineering Research Institute (Neeri)
• Vimta Institute, Hyderabad
• Air quality data will be displayed on the board that gives information about pollution at the gate of the institute.
